We investigate experimentally the discharge of a 2D-silo, Hele-Shaw cell, filled with mono layer ferromagnetic grains submitted to an external magnetic field B perpendicular cell plane. In this case pair interactions are repulsive. show that granular flow rate decreases systematically amplitude applied. Interestingly, while output remains constant during experiment, we reveal very large spatio-...

CONTEXT Anthropogenic vectors enhance the natural dispersal capacity of plant seeds significantly in terms of quantity and distance. Human-mediated seed dispersal (i.e. anthropochory) greatly increases the dispersal of crop species across agroecosystems. In the case of oilseed rape (OSR), spillage of seeds from grain trailers during harvest has never been quantified. METHODS Our experimental ...

The advantages of metal silos in comparison with reinforced concrete are given. Types depending on a wall design considered. construction steel spiral-fold and the method forming cylindrical body general silo is illustrated. Features folding lock, its geometry location described. specifics silo, which affects their stress-strain state, analyzed. Listed two calculation schemes silо complexity in...

Jenis penelitian yang digunakan adalah Penelitian Tindakan Kelas (PTK), terdiri dari 2 siklus. Metode pengumpulan data tes. Berdasarkan penelitian, persentase pra siklus sebe...

Polyphenol oxidase (PPO) is predominately associated with the detrimental effect of browning fruit and vegetables, however, interest within PPO containing forage crops (crops to be fed to animals) has grown since the browning reaction was associated with reduced nitrogen (N) losses in silo and the rumen. The reduction in protein breakdown in silo of red clover (high PPO forage) increased the qu...

In this paper we report experimental results on the granular temperature and velocity profile of glass beads in steady-state flow inside a flat-bottomed silo. We found that dynamics system during discharge is stable mesoscopic scale. particular, ordered directional movement particles can occur near orifice. addition, correlation between distribution vector field opposite radial axial directions...
